A shocking act of terror in downtown Stockholm on Saturday could have been much worse: At a press conference on Monday, Swedish authorities explained that one of the bombs detonated prematurely, narrowly avoiding what would have been a more harmful attack in an area packed with holiday shoppers. As it happened, only the suspect was killed. There appear to have been three bombs that went off, and police say they’re “98 percent sure” that 29-year-old Taimour al-Abdaly, an Iraqi-born resident of Sweden, was the culprit behind the attack. But he may not have worked alone. “From experience, we know that there are usually more people involved in such actions.” Al-Abdaly is a Sunni Muslim and was studying in Britain. His family moved to Sweden from Baghdad in 1992.
